used and Testing of Piles.

Contractor shall also be responsible for ascertaining the Load Carrying

capacities through Relevant Pile testing as specified in these

specifications and as per relevant Indian Standards at specified

frequency.



TERMINOLOGY

Allowable Load:It is load which is applied to a pile after taking into account its ultimate load capacity, pile spacing, Overall bearing capacity of the ground, the allowable settlement, negative skin friction including reversal of

loads. Bearing Pile:A pile formed in the ground for transmitting load of a structure to the soil by the resistance developed at its tips and or along its surface. It is

either vertical or batter pile. It may be ‘End bearing pile’ or friction pile if it supports the load primarily along the surface.

Board Compaction Pile: It is bored cast-in-situ with or without bulb. In this compaction of surrounding ground and freshly filled concrete in pile, bore is

simultaneously achieved by suitable method. A pile with a bulb is called an

“under-reamed bored compaction pile”. Under-reamed pile with more than one bulb is called Multi-under-reamed pile.

Constant Rate of Penetration (CRP) Test:The ultimate bearing capacity of

preliminary piles and piles which are not used as working piles. Constant Rate of Uplift (CRU) Test:The ultimate capacity in tension of

preliminary piles and piles which are not used as working piles. Cut of Level:It is the level where the installed pile is cut off to support the pile caps or beams.

Datum Bar:A rigid bar placed on

immovable supports. Draft Bolt:A metal rod driven into hole bored in timber, the hole being

smaller in diameter than the rod.Drop of Stroke:The distance through which

the driving weight is allowed to fall for driving the piles. Factor of Safety:It is

the ratio of the ultimate load capacity of a pile to the safe load of a pile.

Follower Tube:A tube which is used following the main casing tube and it requires to be extended further. The inner diameter of the follower tube should

be the same as the inner diameter of casing. The follower tube shall preferably

be an outside guide andshould bewater tightwhen driven in water- bearing strata or soft clays.

Initial Test:This test is carried out with a view to determine ultimate

load capacity and safe load capacity. Raker or Batter Pile:The pile which is installed at an angle to the vertical.

Raker piles are normally provided where vertical piles cannot resist the

required applied horizontal forces. The maximum rake to be permitted in piles shall not exceed –



1 in 8 for cast-in-situ piles of large diameter viz. 750 mm dia, and above.

1 in 5 for smaller dia. cast-on-situ piles.

1 in 4 pre-cast piles. Routine Test:It is carried out with a view to check whether pile is capable of taking the working load assigned to it.

Safe Load:It is the load arrived at by applying a factor of safety to the ultimate

load capacity of the pile.

Set:The net distance by which the pile penetrates in the ground due to stated

number of blows of the hammer.

Spliced Pile:A pile composed of two or more lengths secured together, end to end to form one pile.

Test Pile:A pile which is selected for load testing and which is subsequently

loaded for that purpose. This pile may form working pile itself if subjected to a

routine load test with up to one and half time the safe load.

Total displacement (Gross):The total movement of the pile under a given load.

Total Elastic Displacement:This is the magnitude of the displacement of the

pile due to rebound caused at the top after removal of given test load. This

comprises two components as follows:

(a) Elastic displacement of the soil participating in load transfer; and

(b) Elastic displacement of the pile shaft. Trial Piles:These are installed initially to assess the load carrying capacity, it is

either tested to ultimate bearing capacity or twice the estimated safe load. Ultimate Load Capacity:The maximum load which a pile can carry before

failure of ground (when the soil fails by shear) or failure of pile materials.

Working Load:It is a load assigned to a pile as per design. Working Pile:It is a pile forming part of foundation of a structural system.

DSR Item No. 16.68:Providing and laying 60mm thick factory made

cement concrete interlocking paver block of M -30 grade made by block

making machine with strong vibratory compaction, of approved size,

design & shape, laid in required colour and pattern over and including

50mm thick compacted bed of coarse sand, filling the joints with fine

sand etc. all complete as per the direction of Engineer-in-charge.

Material

Concrete Pavers For pedestrian areas, concrete pavers should be Precast and

cured paver blocks of 60mm thickness, ±2mm tolerance in dimensions and

flatness, min. compressive strength 300 kg/sq cm, made from materials

conforming to IS standards.

Sand Bedding

Sand bedding shall be done on 150 mm thick sub grade of compacted bed of 20

mm thick nominal size stone aggregate the paving blocks are indicated in the

Contract Drawings to be bedded on sand (flexible paving). This material shall be

naturally occurring sand or shall consist of crushed rock or gravel or a

combination thereof with naturally occurring sand, hard, clean, free from all

adherent coatings. It shall comply in all respects with relevant Indian Standards

or MORTH code and be well graded down from 5mm. The moisture content of

the laying course should be as uniform as possible and at or about its optimum.

Where material is to be stockpiled it should be covered. The laying course

should be such that, after compaction, it forms a nominally uniform layer, 50mm

thick, below the pavers. It shall be laid in accordance with either of the

following alternative methods: - The material should be spread loose in a

uniform layer and screeded to a thickness required to give nominal 50mm layer



after completion of the paving. OR The material should be spread in a loose,

uncompacted layer to approximately 2/3 of the required final thickness. This

layer should be lightly compacted by means of a vibrating plated compactor. A

further layer of loose material should be spread and screeded to create a loose

surface on to which the units can be placed. Care should be taken to avoid

localized disturbance of the prepared laying course sand by pedestrian or

wheeled traffic prior to placing units. The area of laying course prepared should

be such that the position of its boundary is not more than one meter from the

position of the lying face at the end of the working period wherever practicable.

Joints in Flexible Paving Joints are to be 2mm when placed hand-tight. Pavers

shall be laid working from an existing laying face edge or edge restraint. Full

pavers should be laid first; closure units should then be laid. The area to be laid

should be completed as far as is possible in entire paver units. Wherever

possible, infilling to boundaries and obstructions should proceed as the laying of

the surface course proceeds and infilling should be completed before compaction

commences. Mechanical force shall not be used to obtain tight joints. For

flexible paving sand shall be brushed into the joints until they are filled to the

top surface of the paving blocks. Sand for joint filling should be dry with a

minimum particle size no greater than 1.18mm containing about 10% by weight

passing a 0.75mm sieve. Sand color shall be agreed with EIC prior to brushing

into joints. The Contractor shall allow for cutting units to achieve laying to

curves (without opening up joints).

Laying Pavers

The units shall be laid to the patterns shown in the drawings. Special paver

shapes designed to assist with the formation of boundaries and with changes in

direction may be incorporated with the approval of the EIC.

Cutting Pavers

Paving blocks requiring cutting shall be cut using a diamond blade bench saw to

give an acceptable quality edge to the satisfaction of the EIC and prior to general

cutting taking place on site. Pavers shall be cut to form, neat

junctions/boundaries with other paving materials/kerbs, street furniture, etc.

Fillets of colour matched mortar in lieu of small pieces of unit paving shall be

avoided where possible and only be used with the approval of the EIC. Paving

blocks showing a jagged or irregular edge will be rejected by the EIC and must

be replaced to the satisfaction of the EIC all at the Contractors expense. Care

shall be taken to avoid placing more than one cut kerb and/or paver unit in close

proximity to another cut unit at junctions/changes of direction of paving. The

Contractor must allow for the periodic replacement of blades in cutting

equipment to ensure clean cut edges to paving units.

Mixing Pavers Where there is a colour variation between batches of pavers the

Contractor is to ensure that pavers are mixed to avoid patterning in paved areas



and this shall be to the approval of the EIC. Where patterning occurs the

Contractor shall lift, mix and relay the pavers to the EIC's approval.

Compaction of Flexible Paving Pavers on sand bed shall be subjected to passes

of a steel-faced vibrating-plate compactor to adequately compact the laying

course and to bed and regulate the paving blocks. The vibrating-plate compactor

shall have a centrifugal force of 16-20KN, a plate area of 0.35-0.5 sq m and a

frequency of 75-100Hz. enough passes shall be made to compact the paving

course and produce an even surface. All trimming should be completed before

the area is compacted. Compaction should follow laying as soon as possible but

should not be carried out within 1m of the laying edge. Apart from this edge

strip no area of paving should be left without being compacted at the completion

of the days' work. The EIC's approval must be obtained if compaction is not to

be completed at the end of the day's work.

Finished Levels Finished levels of the paving units shall not deviate by more than

2mm against adjacent units whilst the deviation from the design profile

measured under a 3m straight edge should not exceed 10mm. The units shall

form neat junctions with and prevent damage to adjacent work.

Cleaning on Completion of Work On completion the face of the units must be

clear of all dust, rust and other stains, adhering mortar and other droppings. Any

units from which stains cannot be removed shall be replaced at the Contractors

expense and be to the approval of the EIC. Flexible paving surfaces are to be

brushed down with a soft bristle brush with joints refilled with sand where

required. The paved areas must be left in a neat and tidy condition to the

satisfaction of the EIC.

Additional technical specifications for precast concrete paver blocks

Raw Materials - Cement

The cement used in the manufacture of high quality precast concrete paving

block shall be conforming to IS 12269 (53 grade) ordinary Portland cement or IS

8112 (43 grade ordinary Portland cement). The minimum cement content in

concrete used for making paver blocks should be 380 kg/cu.m.

Raw Materials - Aggregates

The fine and coarse aggregates shall consist of naturally occurring crushed or

uncrushed materials which apart from the grading requirements comply with IS

383-1970. The fine aggregates used shall contain a minimum of 25 % natural

silicon sand. Lime stone aggregates shall not be used. Aggregates shall contain

no more than 3 % by weight of clay and shall be free from deleterious salts and

contaminants.

Raw Materials - Water



The water shall be clean and free from any deleterious matter. It shall meet the

requirements stipulated in IS: 456-2000.

Other materials

Any other material/ingredients used in the concrete shall conform to latest IS

specifications.

Paver blocks characteristics

•The concrete pavers should have perpendicularities after release from the

mould and the same should be retained until the laying.

•The surface should be of anti-skid and anti-glare type.

•The paver should have uniform chamfers to facilitate easy drainage of surface

run off.

•The pavers should have uniform interlocking space of 2 mm to 3 mm to ensure

compacted sand filling after vibration on the paver surface.

•The concrete mix design should be followed for each batch of materials

separately and automatic batching plant is to be used to achieve uniformity in

strength and quality.

•The pavers shall be manufactured in single layer only.

•Skilled labour should be employed for laying blocks to ensure line and level for

laying, desired shape of the surface and adequate compaction of the sand in the

joints.

•The pavers are to be skirted all round with kerbing using solid concrete or stone

kerbs or as directed by the EIC. The kerbing should be embedded for minimum

100 mm depth.

Laying - Priming

It will be the responsibilities of the contractors to ensure that the

manhole/pipeline cable trenches/circular drainage system etc. raised / lowered

to finish paving level using the requisite materials as per instruction of Engineer.

The areas of potholes/deep depressions at the isolated locations also have to be

filled up before laying the paver blocks. No extra pavements will be made for

this purpose.

It will be the responsibility of the contractor to ensure that undulations on the

paver’s blocks are eliminated after the traffic is allowed on it. Proper slope for

drainage of water needs to be ensured by the Contractor. All necessary

materials, tools, tackles are required to be arranged by the Contractor.

Laying - Bedding sand course



The bedding sand shall consist of clean well graded sand passing through 4.75

mm sieve and suitable for concrete. The bedding should be from either a single

source or blended to achieve the following grading;

Sieve size% passing

9.5 mm100

4.75 mm95-100

2.36 mm80-100

1.18 mm60-100

600 microns25-60

300 microns10-30

150 microns5-15

75 microns0-10

Contractor shall be responsible to ensure that single-sized, gap-graded sands or

sands containing an excessive amount of fines or plastic fines are not used. The

sand particles should preferably be sharp (not rounded) as sharp sand possess

higher strength and resist the migration of sand from under the block to less

frequency areas even though sharp sands are relatively more difficult to compact

than rounded sands, the use of sharp sands is preferred for the more heavily

trafficked driveways. The sand used for bedding shall be free of any deleterious

soluble salts or other contaminants likely to cause efflorescence.

The sand shall be of uniform moisture content and within 4 % - 8 % when

spread and shall be protected against rain when stock piled prior to spreading.

Saturated sand shall not be used. The bedding sand shall be spread loose in a

uniform layer as per drawing. The compacted uniform thickness shall be of 45

mm and within +/- 5 mm. Thickness variation shall not be used to correct

irregularities in the base course surface.

The spread sand shall be carefully maintained in a loose dry condition and

protected against pre-compaction both prior to and following screeding. Any pre-

compacted sand or screeded sand left overnight shall be loosened before further

laying of paving blocks take place.

Sand shall be slightly screeded in a loose condition to the predetermined depth

only slightly ahead of the laying of paving unit.

Any depressions in the screeded sand exceeding 5 mm shall be loosened, raked

and rescreeded before laying of paving blocks.

Laying of interlocking paver blocks



Paver blocks shall be laid in pattern specified in drawing throughout the

pavement. Once the laying pattern has been established, it shall continue

without interruption over the entire pavement surface. Cutting of blocks, the

use of infill concrete or discontinuities in laying pattern is not to be permitted in

other than approved locations.

Paver blocks shall be placed on the uncompacted screeded sand bed to the

nominated laying pattern, care being taken to maintain the specified bond

throughout the job. The first row shall be located next to an edge restraint.

Specially manufactured edge paving blocks are permitted or edge blocks may be

cut using a power saw, a mechanical or hydraulic guillotine, bolster or other

approved cutting machine.

Paver blocks shall be placed to achieve gaps nominally 2 to 3 wide between

adjacent paving joints. No joint shall be less than 1.5 mm not more than 4 mm.

Frequent use of string lines shall be used to check alignment. In this regard the

“laying face” shall be checked at least every two meters as the face proceeds.

Should the face become out of alignment, it must be corrected prior to initial

compaction and before further laying job is proceeded with.

In each row, all full blocked shall be laid first. Closure blocks shall be cut and

fitted subsequently. Such closer blocks shall consist of not less than 25 % of full

blocks.

To infill spaces between 25 mm and 50 mm wide concrete having screened sand,

coarse aggregate mix and strength of 45 N/sq.mm shall be used. Within such

mix the nominal aggregate size shall not exceed one third the smallest

dimension of the infill space. For smaller spaces dry packed mortar shall be

used.

Except where it is necessary to correct any minor variations occurring in the

laying bond, the paver blocks shall not be hammered into position. Where

adjustment of paver blocks, necessary care shall be taken to avoid the

premature compaction of the sand bedding.

Initial Compaction:After laying the paver blocks, they shall be compacted to

achieve consolidation of the sand bedding and brought to design levels and

profiles by not less than two (2) passes of a suitable plate compactor.

The compactor shall be a high-frequency, low amplitude mechanical flat plate

vibrator having plate area sufficient to cover a minimum of twelve paving blocks.

Prior to compaction all debris shall be removed from the surface.

Compaction shall proceed as closely as possible following laying and prior to any

traffic. Compaction shall not, however, be attempted within one meter of the

laying face. Compaction shall continue until lipping has been eliminated between

adjoining blocks. Joints shall then be filled and re-compacted as described in

relevant Clause.



All work further than one meter from the laying face shall be left fully compacted

at the completion of each day’s laying.

Any blocks that are structurally damaged prior to or during compaction shall be

immediately removed and replaced.

Sufficient plate compactors shall be maintained at the paving site for both

bedding compaction and joint filling.

Joint filling and final compaction:

As soon as possible after compaction and in any case prior to the termination of

work on that day and prior to the acceptance of vehicular traffic, sand for joint

filling shall be spread over the pavement.

Joint sand shall pass a 2.36 mm (No. 8) sieve and shall be free of soluble salts

or contaminants likely to cause efflorescence. The same shall comply with the

following grading limits

Sieve size% passing

2.36 mm100

1.18 mm90-100

600 microns60-90

300 microns30-60

150 microns15-30

75 microns10-20

The Contractor shall supply a sample of the jointing sand to be used in the

contract prior to delivery and such materials to site for incorporation into the

works. Certificates of test results issued by a recognized testing laboratory

confirming that the samples conform to the requirements of this specifications

shall accompany the sample.

The jointing sand shall be boomed to fill the joints. Excess sand shall then be

removed from the pavement surface and the jointing sand shall be compacted

with not less than one (1) Pass by the plate vibrator and joints refilled with sand

to full depth. This procedure shall be repeated until all joints are completely

filled with sand. No traffic shall be permitted to use the pavement until all joints

have been completely filled with sand and compacted.

Both the sand and paver blocks shall be dry when sand is spread and boomed

into the joints to prevent premature setting of the sand.

The difference in level (lipping) between adjacent blocks shall not exceed 3 mm

with not more than 1 % in any 3 m x 3 mm area exceeding 2 mm. Pavement



which is deformed beyond above limits after final compaction shall be taken out

and reconstructed to the satisfaction of the Engineer.

Edge Restraint

Edge restrains need to be sufficiently robust to withstand override by the

anticipated traffic to withstand thermal expansion and to prevent loss of the

laying course material from beneath the surface course. The edge restraint

should present a vertical face down the level of the underside on the laying

course.

The surface course should not be vibrated until the edge restraint together with

any bedding or concrete hunching has gained sufficient strength. It is essential

that edge restraints are adequately secured.

Concrete Block Making Machine

The block making machine should ensure the following:

High degree of dimensional accuracy (± 3 mm)

Precast blocks with spacer nibs (23 mm to ensure uniform joints)

High compaction energy (to produce blocks with high compressive strength)

The above can be generally achieve by machine with following feature –

Block making machine should have simultaneously application of high intense

vibration to moulds at 3000 V.P.M. and hydraulic pressure 800 psi

Concrete Batching & Mixing Plant

The concrete Mix design should be followed for each batch of materials. The

concrete ingredient should be mixed in concrete Batching & Mixing plant with

suitable capacity. The plant should be equipped with automatic control panel for

maintaining water cement ratio from batch to batch to obtain concrete of

uniform quality and strength. The plant should be equipped with adequate

mechanism for mechanized loading on raw materials into mixer and conveyor

belt for transportation of concrete from mixer to concrete block making machine.

Sampling and testing procedures for paver blocks

Sample size

Average of minimum 3 samples per 5000 blocks shall be provided for testing.

Sampling for testing:

Sampling for testing of paver blocks shall be done in accordance with relevant

Clause.



Compressive Strength:

Testing for compressive strength shall be undertaken in accordance with

Appendix-B. The average compressive strength of the 80 mm. thick paver blocks

tested shall be 50 N/Sq.mm and average compressive strength of the 60 mm.

thick paver blocks tested shall be 45 N/Sq.mm.

Water Absorption:

Testing for water absorption shall be in accordance with IS: 2185: 1979: Part-

(Specifications for Concrete Masonry Blocks) Appendix C.

Sampling of Paver Blocks

Method of sampling:

Before laying paver blocks, each designated section comprising not more than

50,000 blocks shall be divided into ten approximately equal groups. Nine blocks

shall be drawn from each group.

Marking and Identification:

All samples shall be clearly marked at the time of sampling in such a way that

the designated section of part thereof and the consignment represented by the

sample are clearly defined.

The sample shall be dispatched to the approved test laboratory taking precaution

to avoid damage to the paving in transit. Protect the paving from damage and

contamination until they have been tested. The samples shall be stored in water

at 20 ºC + 5 ºC for 24 hours prior to testing.

Procedure for testing of compressive strength for paver blocks

Testing machine:

The testing machines shall be of suitable capacity for the test and capable of

applying the load at the rate specified. It shall comply as regards repeatability

and accuracy with the requirements of relevant IS Specification.

Procedure:The sample specimens shall be tested in wet condition after being

stored for at least 24 hours in water maintained at a temperature of 20 ºC + 5

ºC before the specimens are submerged in water, the necessary area shall be

determined.

The plates of the testing machine shall be wiped clean and any loose girt or

other material removed from the contact faces of the specimen. Plywood

normally 4 mm. thick shall be used as packing between the upper and lower

faces of the specimen and the machine plates and these boards shall be larger

than the specimen by a margin of at least 5 mm at all points. Fresh packing

shall be used for each specimen tested. The specimen shall be placed in the



machine with the wearing surface in a horizontal plane and in such a way that

the axes of the specimen are aligned with those of the machine plates. The load

shall be applied without shock and increased continuously at the rate of

Approximately 15 N/sq.mm per minute until no greater load can be sustained.

The maximum load applied to the specimen shall be recorded.

Calculation of corrected strength:

The compressive strength of each block specimen shall be calculated by dividing

the maximum load by full cross section area and multiplying by appropriate

factors.

Thickness and chamfer correction factors for compressive strength

Work size thickness (mm)Correction Factors

Plain blockChamfered block

601.001.06

801.121.18

Compressive strength calculation

The average corrected compressive strength for the designed block section shall

be calculated.

Method for the determination of water absorption

The test specimens shall be completely immersed in water at room temperature

for 24 hours.

The specimens shall then be weighed, while suspended by a metal wire and

completely submerged in water.

They shall be removed from the water and allowed to drain for one minute.

Visible surface water should be removed with a damp cloth and immediately

weighed.

Subsequent to saturation, all specimens shall be dried in a ventilated oven at

100 to 115 ºC for not less than 24 hours and until two successive weightings at

intervals of 2 hours show an increment of loss not greater than 0.2 percent of

the last previously determined mass of the specimen.

Calculate the absorption as follows -

Absorption, kg/cum = A – B x 1000

A – C



Absorption, percent = A – B x 100

BWhere;

A = Wet mass of unit in Kg.

B = Dry mass of unit in Kg and

C = Suspended immersed mass of unit in Kg

Measurement

Precast concrete paving shall be measured in square meters of finished paved

area, accurate to the nearest centimeter in each direction.

MR 2.007 : Removing from one location, a tree of girth not more than 60

Cms. Including the roots by excavating earth around the root, lifting the

tree along with earth around the roots by suitable equipment,

transporting the tree from old location to the new location, making a pit

of required diameter and depth in earth at new location, and replanting

the tree in to the pit, back filling the soil around the roots of the tree,

including necessary manure, watering the tree for required time till the

roots gets hold in the earth at new location complete as directed by

Engineer In charge.

Tree transplantation is a complex process, and depends on numerous factors.

The entire process of tree transplantation can be divided into the following

stages:

I. Identification of tree species suitable for transplantation

II. Identification of factors affecting tree transplantation

III. Pre-transplantation process

IV. Manufacturing EM solution

V. Transplantation equipment list

VI. VI.Transplantation process on existing host site



VII. VII.Transplantation process on new host site

VIII. VIII.Post-transplantation care

Stage I: Identification of tree species suitable for transplantation

Different tree species have different suitability to adapt to transplantation. The

following hierarchy may be followed for identifying trees suitable for

transplantation:

1.Trees having aerial roots are best adapted to transplantation, as they can grow

new roots easily after the old ones are cut-off. Trees of Ficus family fall under

this category.

2.Palms and palm like trees, having collar root system, are next best suited for

transplantation. One reason for this is that most palms brought from the nursery

are in fact large sized plants that are transplanted from nursery to the site

initially.

3.Trees having a hard bark have the 3rd order of preference for transplantation.

A hard bark prevents drying up of the moisture retained in the trunk. In

addition, the veins of trees having hard bark are located towards the center of

the trunk, as compared to trees with softer barks, whose veins are located

towards the outer part of the bark. Trees like Neem, Peepul, Cassias,

Peltophorum, etc fall under this category.

4.The last preference for transplantation is given to trees having soft barks.

Trees with soft barks have veins in the trunk towards the outer side & hence are

prone to drying up easily during & after transplantation. Trees like Kapok fall in

this category.

In addition to this, one must also look at the sizes of the trees that may be

transplanted. A normal crane (up to 10 tonnes) can move a tree having trunk up

to 45 cm in diameter. For larger trees, one needs to have either a heavy duty

crane or two cranes, and the entire process becomes more complex. Further, the

cost of transplanting larger trees is very high, and it may be found economical to

cut the tree’s branches and re-plant each branch individually, thus obtaining

more trees from one tree.

Stage II: Identification of factors affecting tree transplantation

Trees are immobile living organisms and hence form very specific relationships

with their surrounding ecosystem (climate, animate & inanimate objects). The

growth habit of each tree is dependent on factors such as climate, surrounding

objects & trees, general activity in the area, orientation to the sun, wind

directions on site, insolation period on site, etc. A brief description of major

factors affecting the tree growth & sustenance are discussed below:

1.Insolation:The foliage of each tree is adapted to the daily & seasonal insolation

on the site. Hence, if the site is surrounded by large buildings or trees, and the



tree receives sunlight only during noon, it will have more leaves towards the top

of the canopy. Similarly, if the tree receives sunlight only during afternoon, it

will have more density of leaves toward the west & south-west. This information

is stored in the tree, and it reproduces leaves and grows keep the above factor

in mind.

2.Wind:As the trees grow taller, they have to resist increasing force of wind. If

the region generally receives strong winds from the south-west, the tree will

have a root system developed in order to support it specifically from that

direction. In addition the tree may also have a slight tilt in the direction opposite

to the wind direction, due to continued force of wind over years. Further, local

wind pattern is affected by surrounding buildings or trees, and the trees are

adapted to the same.

3.Soil:Trees older than 3 years absorb not just water, but also humidity from the

soil. While water may be available at greater depths, the top roots of the tree

are adapted to absorb moisture from the soil. Similarly, roots in different parts

are adapted to absorb moisture, water, and nutrients as available on the site.

Thus, the entire root system development is very specific to the site, and the

tree’s growth is dependent on the nutrients usually available to it.

4.Culture: Micro-organisms in the soil provide necessary nutrients to the tree

directly or indirectly. This culture is very important for tree growth and dictates

the growth strategy of the tree.

Selecting the right season for transplantation

In addition to the above process it is very necessary to choose the right season

for transplantation. In tropical India, December to February is the best season

for transplantation as there is no precipitation, low soil moisture (so that soil is

light & easy to transplant), dry weather and most trees are in dormant state

during winter, which reduces their interaction with the surroundings. It is also

easier to dig soil & retain it during transportation during this season.

However, if site conditions require transplantation during other seasons, one

should try to induce dormancy in the tree in order to reduce its relation with the

surroundings before transplantation. This can be achieved by:

-Removing fruits & flowers by applying chemicals

-Digging a moat around the tree & filling it with water+urea or water+cactus

milk solution forcing the tree to shed fruits and flowers and go into dormancy

After a few weeks the tree will become dormant & it will be able to bear the

effect of transplantation easily

Stage III: Pre-transplantation process



Each tree selected for transplantation needs to be conditioned before the actual

transplantation process. The conditioning process lasts between 17-19 days,

depending on the equipment & material availability. Keeping the factors

shortlisted in stage-II in mind, the following actions are taken:

1.The first step is to modify the soil pH. Soil pH is critical for tree growth. If the

pH is acidic, the root development is accelerated. A slightly acidic pH (between

6.5 & 7.2) is favorable for the transplantation process. This is achieved by using

SO2 (Sulphur dioxide), distilled water or cactus milk, which are poured or

sprinkled around the tree in definite quantities (which are decided by the

horticultural expert based on tree species, age and size). The site is left

untouched for 2 days to allow the pH to change gradually.

2.The next step is to change the bacterial culture of the soil. One can prepare an

EM (effective micro-organisms) solution or buy the same in powder or liquid

form from the market. This solution is poured around the tree and sprayed on its

leaves & trunk. The solution is re-applied after a period of 7 days. After 15 days

of first application of the EM solution, the tree is generally ready for the

transplantation process.

3., on advise of horticultural expert, one may start chopping off few branches

every 3-4 days to allow the tree to recuperate from the loss of branches

gradually. The aim is to chop off most of the larger branches of the tree before

transplantation.

Stage IV: Manufacture of EM solution

While processed EM solution is available in market in powder & liquid form, it is

always best to prepare a fresh solution from the native regions of the tree

species. The following are the steps of production:

-Identify a natural habitat of the tree species to be replanted, and look out for

healthy trees of the same species in that region, in locations that are not

frequented by humans. Collect about one kg of soil, mulch, leaf and other

natural matter from near the trees. If such an area cannot be identified, the soil

& mulch around the Rayan (Manilkara hexandra) tree can be used, as it is

excellent culture raw-material.

-Procure an industrial mixing drum (about 50-100lts) and put the soil & mulch

mixture in it. Buy some desi jiggery (dark brown to black colored – none

processed) – essentially glucose, and put it in with the mixture. Pour water and

stir the mixture for some time. Add cow-dung (from wandering cows, not from

those in cowsheds) and dal (protein) and stir the mixture again.

-The culture has to be left for 15 days with occasional stirring. After 15 days, the

culture is ready for use.



-The culture should be used in 1:10 proportion of culture: water, applied and

sprayed around and on the tree.

Stage V: Transplantation equipment list

The following equipment and materials need to be procured before the start of

the transplantation process:

-EM solution required before transplantation

-SO2, distilled water or cactus milk required before transplantation

-CuS solution as fungicide

-Heavy Crane for lifting the tree, based on tree height & weight (with operator

experienced in tree transplantation process)

-Truck for transporting the tree

-10-15 labourers

-JCB lifting machine

-Diamond tipped road-breaker if tree is on an existing road

-Jet spray pump with 15’-20’ throw range

-1 process engineer or horticultural expert

-Tractor for balancing tree by providing push-pull force

-Steel or MS pipe or angle section for support at new host site

-1” thick rope and link-chain to hold tree onto the crane

-Cotton waste for buffer between tree and link chain

-Gunny bags or cotton / plastic tarpaulin for holding the tree’s bulb

-Axe and ladder for chopping off the branches

-Fungicide Diythen M-45

Stage VI: Transplantation process

Tree transplantation is a very sensitive process for the tree, and one needs to

perform it patiently. Hurried transplantation may lead to death of the tree

subsequently. The process is performed in two steps. The first step takes place

on the existing host site, and the second step takes place on the new host site.

Part-I : existing host site



1.North direction is marked on the tree with marker or chalk, and the bent of

tree to the ground along with direction of bent is noted

2. A sketch of surroundings is made, so that similar conditions may be

reproduced on the new host site.

3.The original foliage of the tree is marked on the ground with chalk powder,

and approximately half of that is marked for digging. If the tree is large (>4-

5m), a square of 2mx2m is marked with the tree in center, for digging.

4.If there is road, it needs to be cut with diamond cutter, and then the marked

area has to be dug manually up to 1m depth.

5.The process engineer or horticultural expert will observe the collar rooting of

the tree at this depth and decide on the total depth of digging. The depth of the

collar is about 2’-3’ below the first root. However, if the site has been filled after

the tree has been planted; the collar may be much lower, at the original level of

the site. The bulb of the tree is preserved within this collar.

6.The branches of the tree are now trimmed to half their size with an axe, and

sand, soil and fungicide (CuS) is applied on the tip of the cut branch and up to 2’

from tip on the entire branch surface. Clay-dung mixture may also be applied in

place of fungicide.

7.Step 6 may be performed over a period of 3-5 days for best results, starting a

week before the transplantation day.

8.After identifying the depth of digging, the rest of digging is carried out with

JCB.

9.After the JCB has cut roots from below desired depth, the trunk is buffered

with cotton waste and the crane lifts the tree up in the same place.

10.At this time, the labourers cover the bulb and soil with gunny bag or

tarpaulin, and it is tied to the trunk.

11.The tree may be balanced using a tractor if required, and it is set onto the

truck.

12.The truck has a soil slope created on it in advance, sloping downwards from

the driver cabin.

13.The tree is laid on this soil at 45 degrees to vertical and transported to new

host site.

Step II: New host site

-Before the tree is brought on the new host site, a pit equal to the size of the

tree’s bulb is dug on-site and kept ready to receive the tree.



-It is very important NOT to apply urea or any nitrogen based fertilizer to the pit

at this stage.

-When the tree is brought on site, a crane lifts the tree from the truck and holds

it over the pit, aligned with the north in the same manner as that on its original

site.

-The labourers remove the tarpaulin or gunny bags and spray fungicide on the

bulb. If gunny bags are used, they may be left on the tree bulb, as they

disintegrate naturally.

-The tree is then lowered into the pit and surrounding pit is backfilled with soil

taken out during digging.

-Light spraying of water should be done, but away from the bulb of original soil.

The original bulb needs to be preserved for a few days with same levels of soil

moisture & soil air without allowing soil to settle. If the soil bulb settles during

this process, it must be filled with fine soil from original soil and some water

should be sprinkled. Care should be taken that over-sprinkling should not

destroy the soil bulb.

-Apply a coat of CuS wherever wear & tear has happened on the tree during the

transplantation process, and cover these areas with cloth to avoid excess

transpiration.

-Install the steel or MS pipe / angle support to align tree with vertical as it was

on original site.

Stage VII: Post-transplantation care

-First watering should be done after 3 days of transplantation.

-Next watering should be done after 10 days of transplantation, and mulch

should be added on the surface to maintain soil moisture.

-When possible one should try to recreate surrounding conditions similar to that

of original host site around the new host site. Hence, if the tree was surrounded

by tall buildings, it should be transplanted in a similar location or one should

erect scaffolding with high shuttering for few weeks around the tree to simulate

such conditions.

-Such simulations may be removed gradually over a few weeks to allow the tree

to adapt to changing surroundings.

Measurement shall be per tree transplanted, irrespective of size. The rate

includes the cost of all materials, equipment, labour, carting, loading &

unloading, removal of debris to local specified within the site, involved in all the

operations described above.

1.0Material.

The primary raw material for the production of CSEB is raw earth or soil. OPC

cement in small quantities and water are other constituents. Coarse sand or stone dust may be added depending on soil quality. Soil is made up of grains of various sizes. The grain size distribution of a soil determines its suitability for the

manufacture of CSEB. The production of CSEB is based on the principle of densification of raw earth

mixed with stabilizer (cement or lime) in small quantities ranging from 5-10% by weight of the mix. The production process incorporates 3 main stages

Mix Preparation Compaction Post Production

Sieving Filling the mould Humid and wet curing

Batching Moulding Final storage

Mixing Block ejection and

stacking

Transportation

Technical Data

The performance specifications of CSEB are based on B.I.S code and tested in

accordance with IS 1725, 1982 and IS 3495-1992.

Techno-economic characteristics Specifications

Dimensional Variation +/-2 mm

Soaked characteristic compressive strength 7.5 MPa

Water absorption <15% by weight

Erosion <5% by weight

Surface characteristics No pitting on the surface

2.0Procedure for Manufacturing: Soil sand cement are to be taken as per above proportion and mixed thoroughly

in a rotary pan mixer. Water to be added in the mixer in such proportion that the

resultant moisture content of the mix is approximately 10 to 12%. The soil is

then compressed and moulded in Earth Blocks of size 230 mm x 110 mm x 100

mm size on a Vibratory Hydro Mechanical press to achieve Compression pressure

of 2.7 to 5 MPa to obtain the compression ratio of 1.7 to 1.8 in the blocks. The

blocs must be cured with moist air or by covering with water soaked gunny bags

over the stake of earth blocks for four weeks. The Blocks are allowed to dry for

at least 10 days under the shade. The blocks are ready for use in the Masonry.



Before the use of blocks in masonry, samples from each stake of Blocks must be

tested for its compressive strength. If the Soaked characteristic Compressive

strength of the blocks tested is equal to or more than 7.5 MPa then only the

same should be used for masonry. The earth blocks not satisfying the strength

criteria may be rejected and recycled.

The stages of the manufacturing process are as follows:

3.0 INGRADIENTS

pipe trenches at the site shall be used. Soil shall be dumped at block making

yard. Soil shall be collected from 50cm below natural ground at site to avoid

high organic content in soil. While dumping the soil it is essential to make sure

that one dump (heap) is from the single identified source of soil. The soil dump

shall not have more than 150 m3 of soil for testing purpose. The representative

sample from every dump shall be tested thoroughly for grain size distribution.

(Including bifurcation of silt and clay), liquid limit, plastic limit and swelling

index. Soil should be thoroughly soaked/submerged into water so that all lumps of soil

dissolves. When soil settles down, excess water needs to be drain out. This wet soil

should be used to prepare premix for the block making.

1 Scaffolding For all exposed brick work, tile work or stone work independent double

scaffolding having two sets of vertical supports shall be provided. The supports

shall be sound and strong tied together with horizontal pieces over which scaffolding planks shall be fixed. For all other work in building, single scaffolding shall be permitted. In such

cases, the inner end of the horizontal scaffolding pole shall rest in a hole provided only in the header course for the purpose. Only one header for each pole shall be left out. Such holes for scaffolding shall, however, not be allowed in

pillars/columns less than one metre in width, or immediately near the skew backs of arches. The holes left in masonry works for scaffolding purposes shall be filled and made good before plastering.

Note:In case of special type of work, scaffolding shall be got approved from Engineer-in-Charge in advance.

2 Preparation of surface The joints shall be raked out properly. Dust and loose mortar shall be brushed out. Efflorescence if any shall be removed by brushing and scraping. The surface

shall then be thoroughly washed with water, cleaned and kept wet before pointing is commenced. In case of concrete surface if a chemical retarder has been applied to the form

work, the surface shall be roughened by wire brushing and all the resulting dust and loose particles cleaned off and care shall be taken that none of the retarders is left on the surface.

The joints shall be raked to such a depth that the minimum depth of the new mortar measured from either the sunk surface of the finished pointing or from the edge of the brick shall not be less than 12 mm.



3 Mortar

Mortar of specified mix shall be used. It shall be as specified under Chapter 3.0. 4 Application and Finishing 4.1 The mortar shall be pressed into the raked out joints, with a pointing trowel,

either flush, sunk or raised, according to the type of pointing required. The

mortar shall not spread over the corner, edges or surface of the masonry. The pointing shall then be finished with the proper tool, in the manner described

below:

4.2 Flush Pointing:The mortar shall be pressed into the joints and shall be finished off flush and level with the edges of the bricks, tiles or stones so as to

give a smooth appearance. The edges shall be neatly trimmed with a trowel and straight edge. 4.3 Ruled Pointing : The joints shall be initially formed as for flush pointing

and then while the mortar is still green, a groove of shape and size as shown in drawings or as instructed, shall be formed by running a forming tool, straight

along the centre line of the joints. This operation shall be continued till a smooth and hard surface is obtained. The vertical joints shall also be finished in a similar way. The vertical lines shall make true right angles at their junctions with the

horizontal lines and shall not project beyond the same. 4.4 Cut or Weather Struck Pointing:The mortar shall first be pressed into the joints. The top of the horizontal joints shall then be neatly pressed back about 3

mm or as directed, with the pointing tool so that the joints are sloping from top to bottom.

The vertical joints shall be ruled pointed. The junctions of vertical joints with the horizontal joints shall be at true right angles. 4.5 Raised and Cut Pointing : Raised and cut pointing shall project from the

wall facing with its edges cut parallel so as to have a uniformly raised band about 6 mm raised and width 10 mm more as directed. 4.6 The superfluous mortar shall then be cut off from the edges of the lines and

the surface of the masonry shall also be cleaned off all mortar. The finish shall be such that the pointing is to the exact size and shape required and the edges are straight, neat and clean.

5 Curing The pointing shall be kept wet for seven days. During this period it shall be

suitably protected from all damages. The pointing lines shall be truly horizontal and vertical except where the joints are slanting as in rubble random masonry. Lines of joints from different

directions should meet neatly at the junctions instead of crossing beyond. 6 Measurements 6.1 Length and breadth shall be measured correct to a cm and its area shall be

calculated in square metres up to two places of decimal. 6.2 The various types of pointing for example, struck, keyed, flush, tuck, etc. shall each be measured separately.

permission obtained from the Engineer-in-Charge.

1.Commencing Work

Painting shall not be started until the Engineer-in-Charge has inspected the

items of work to be painted, satisfied himself about their proper quality and

given his approval to commence the painting work. Painting of external surface

should not be done in adverse weather condition like hail storm and dust storm.

Painting, except the priming coat, shall generally be taken in hand after

practically finishing all other building work.

The rooms should be thoroughly swept out and the entire building cleaned up, at

least one day inadvance of the Paint work being started.



2.Preparation of Surface

The surface shall be thoroughly cleaned and dusted off. All rust, dirt, scales,

smoke splashes, mortardroppings and grease shall be thoroughly removed

before painting is started. The broken edges, undulations etc. can be rectified by

using a paste made of Spectrum Rectochem Surface Improver mixed with

ordinary Portland cement at the ratio of 1:1.

The prepared surface shall have received the approval of the Engineer-in-Charge

after inspection, before painting is commenced.

3.Application

Before pouring into smaller containers for use, the Paint shall be stirred

thoroughly in its

Containers, A coat of is applied after cleaning the surface thoroughly. The

primer is to be diluted with water at the rate of 1:4, i.e. one part of primer and

four parts of water. It should be applied liberally so that the absorption

becomes uniform. Thereafter the material (Law pigmented texture paints of

Spectrum or approved equivalent) shall be applied with trowel onto the surface.

The final painting shall be done by spraying, using Spray Plaster Gun. Spray

machine used may be (at high pressure (small air aperture) type, or (b) at low

pressure (large air gap) type, depending on the nature and location of work to

be carried out. Skilled and experienced workmen shall be employed for this class

of work.

Spraying should be done only when dry condition prevails. Each coat shall be

allowed to dry out thoroughly and rubbed smooth before the next coat is

applied. This should be facilitated by thorough ventilation. Each coat except the

last coat, shall be lightly rubbed down with sand paper or fine pumice stone and

cleaned off dust before the next coat is laid.

No left over Paint shall be put back into the stock tins. When not in use, the

panels, angles of mouldings etc. shall be left on the work.

4.Brushes and Containers

After work, the brushes shall be completely cleaned of Paint and linseed oil by

rinsing with turpentine. A brush in which Paint has dried up is ruined and shall

on no account be used for painting work. The containers when not in use, shall

be kept closed and free from air so that Paint does not thicken and also shall be

kept safe from dust. When the Paint has been used, the containers shall be



washed with water and wiped dry with soft clean cloth, so that they are clean,

and can be used again.

5.Measurements

The length and breadth shall be measured correct to a cm. The area shall be

MR 12.005 : Providing and applying breathable, non-reactive,

antifungal, and water repellent Silane/ Siloxane chemical as approved

by Engineer-in-charge, of approved make, diluted with solvent mineral

Turpentine oil in the ratio of 1:12 (One part of approved chemical :12

Part of Turpentine oil), on the existing stone masonry surface or Stone

cladding or RCC surfaces with two or more coats to give uniform

application of chemical on the surface, including scaffolding, curing,

cleaning the surfaces and other incidental work to be done etc. complete

at all levels as directed by engineer in charge.

1.Material

Water repellent is a premium water based or solvent based, high performance,

long lasting exterior paint specially formulated for application on highly

absorbent surfaces. The product is based on 100% Acrylic resin and hence it

forms a tough and flexible protective film, with an excellent bonding to the

substrate, which are released slowly over a long period of time. This actively

helps not only to prevent the fungal and algae growth, but also ensures constant

surface activity against these irritants for a long period.

Excellent out-door durability.

Excellent adhesion on absorbent surfaces.

Very good color retention.

Faster drying.

Smooth with Sheen finish.

Excellent resistance to fungal and algae growth..

Easy to apply and maintain.

Superior wash ability& scrub resistance.

Very wide range of beautiful colors.

Very good coverage thus good value for money.



2. PreparationofSurface

The surface to be painted must be free of all dust grease, traces of paint flakes,

algae, fungus, etc. The surface previously coated with paint must be cleaned

thoroughly with a stiff wire brush, to remove dust, dirt, chalking or any friable

material & loose flakes. Wash thoroughly with water and allow to dry. This

ensures proper adhesion of the new paint system. In case of fungus affected

area apply a liberal coat of Fungicidal Solution. Allow it to react for minimum 6 -

8 hrs.

Processing

Flooding, preferably not under pressure, is the best technique for applying water

repellent, which is ready to use after dilution. Apply several coats, wet on wet,

until the substrate is saturated. Generally, at least two applications suffice for all

substrates. Do not leave long breaks between coats. Apply the next when the

substrate has absorbed the previous one and is no longer shiny (wet-on-wet

working). The substrate must not have damp spots, i. e., it should look dry. The

requisite quantity of water repellent depends on the absorbency of the substrate.

The amount of impregnating agent required for a substrate and the effectiveness

of the impregnation should be determined on site by testing a small area of the

material to be treated. Before applying water repellent, be sure to cover

windows and other non-absorbent surfaces properly because the product cures

so quickly that it will be extremely difficult, if not impossible, to remove after a

few hours. Wipe off any splashes on window panes immediately, using a solvent

if necessary

3. Dilution

The solvents best suited for diluting water repellent are aliphatic hydrocarbons

(e. g. White Spirit 130/175), aromatic hydrocarbons (solvent naphtha, e. g.

Shell sol A) or low-odor is paraffin hydrocarbons (e. g. Isobar H) or as per

manufacturer specifications. The solvent used should have a boiling range of 140

– 190 °C and an evaporation number of 30 – 90. If the above-mentioned

hydrocarbon solvents are used, water repellent should be diluted in a weight

ratio of 1: 11 to 1: 15 or as per manufacturer specifications. Anhydrous alcohols,

such as ethanol or 2-propanol, could also be used and are even indispensable

whenever contact of the impregnating agent with solvent-sensitive materials

(such as expanded polystyrene, bitumen, etc.) cannot be avoided. The alcohol

must be completely anhydrous. If alcohol is used as a solvent, a dilution ratio of

1: 12 pbw is recommended or as per manufacturer specifications. When

impregnating slightly damp substrates, water repellent will give better results if

diluted with hydrocarbons than with alcohol. Stir vigorously when adding the

diluent to water repellent. Since water repellent reacts with humidity, prolonged

contact with air must be avoided. The containers must be hermetically sealed.



4. Storage

Water repellent has a shelf life of at least 12 months when stored between 0 °C

and 30 °C in the tightly closed original container. The containers must be

protected against direct sunlight. The 'Best use before end' date of each batch

appears on the product label. Storage beyond the date specified on the label

does not necessarily mean that the product is no longer usable. In this case

however, the properties required for the intended use

MR 12.006 : Extra for expose shuttering over ordinary shuttering for

exposed concrete elements using special sized of approved quality steel

plates formwork / 12 mm waterproof plywood formwork / wood grain

finish formwork with definite pattern as per approved drawing,

Including providing and fixing necessary sleeves, grooves & Drip moulds

for all shapes, at all levels and as directed by engineer in charge. Same

kind of shuttering material should be used for standard and residual

sizes. (no separate payment for small qty. in Meter)

1.Material

Steel Sheeting and steel platesSteel sheeting and steel plates (black sheet)

should be free from clinks, twists, offsets, warps, etc. Their surface should be

neat, clean and smooth.

The size of angles/tubes used for framing and bracing of steel plates should be

sufficient to withstand the Weight of concrete without forming clinks, twists,

offsets, warps, etc. in the steel plates. Also, the gauge of steel sheeting used

should not be less than 16 G.

Minimum two bracing angles should be provided along with angle framing while

making the steel plates. It should be welded at all four corners and at junction of

angle framing and bracing.

If the plates are to be welded, steel sheet and angle framing/bracing should be

welded from sides and at back. Welding on sides should be buffed to make the

sides smooth. Also, intermittent welding should be done to keep steel sheet and

angle framing/bracing in one plane.

It shall be made from strong and selected hard woods. It shall be bonded with

high quality Phenol Formaldehyde synthetic resin adhesive, hot pressed and then

shall be funkier treated with a permanent Type of preservative by vacuum cum

pressure impregnation.

Waterproof plywoodMarine Plywood of std. company (film faced waterproof)

used for exposed formwork shall be minimum 12 mm thickness and as per

requirement up to 25 mm thickness as directed by engineer in charge The



quality plywood complying with IS :4990 and of make approved by the Engineer

in charge.

Due to the bonding with Phenol Formaldehyde, it shall be moisture and

weatherproof. The use of selected hard woods renders hard and wear resistant

faces (Film faces waterproof plywood) and thereby it shall be reusable several

times. It shall be highly resistant to rot, termites and other wood inhabiting

insects. Due to complete penetration of the preservative, it shall be exceedingly

durable.

The shuttering shall be supported on wooden battens at distance as required as

per thickness of plywood and as directed by engineer in charge.

It shall have high impact strength and therefore shall be used successfully in

place of timber planks and steel sheets. It shall protect the concrete from rapid

temperature changes and shall provide optimum conditions for setting of the

concrete. As it shall possess remarkable design flexibility, it shall be ideal for

curved formwork.

Fair finish with wood grain exposed finish surface wood grain planks of deodar,

pine or equiv. Wood shall be used to give a pattern as per drawing by cutting it

in size and finishing smooth on all faces. Wood grin planks thickness should not

be less than 30 mm otherwise specified. Suitable stiffeners and walers shall be

provided depending on the shuttering design. It shall be stable and not liable to

warp when exposed to sun and rain or wetted during concrete

Precaution measures

Before placing concrete, forms shall be thoroughly cleaned off of all rust, dust

and loose materials. Colorless oil or grease or chemical of approved quality shall

be applied of approved manufacture as directed by engineer in charge before

placing steel.

The surface of timber shuttering that would come on contact with concrete shall

be well wetted and coated with raw linseed oil or oil of approved manufacture as

directed by engineer in charge. In case of steel shuttering, either raw linseed oil

or oil of approved manufacture as directed by engineer in charge shall be applied

after thoroughly cleaning the surface. Under no circumstances, black or burnt oil

shall be permitted.

Fair finish with a uniform texture and definite pattern as per drawing for exposed

concrete elements. The surface shall be neat and free from physical irregularities

and imperfections. Since there will not be any plaster to cover concrete

members formed under this finish, the work shall be more precise in terms of

finish line, level & plumb.

The shuttering shall be supported on battens and beams and props properly

cross braced together, so as to make the centering rigid. The shuttering shall



have smooth and even surface and its joints shall not permit leakage of cement

grout.

Double wedges shall further be provided between the sole Plate and the props so

as to facilitate tightening and easing of shuttering without jerking the concrete.

The timber used in shuttering shall not be so dry as to absorb water from

concrete and swell or bulge nor so green or wet as to shrink after erection. The

timber shall be properly sawn and planned on the sides and surface coming in

contact with concrete. Wooden form work with metal sheet lining or steel plates

stiffened by steel angles shall be permitted.

As far as possible, clamps shall be used to hold the forms together and use of

nails and spikes shall be avoided.

If at any stage of work, during or after placing concrete in the structure, the

form work sags or bulges out beyond the required shape of the structure, the

concrete shall be removed and work redone with fresh concrete and adequately

rigid form work. The complete form work shall be got inspected by and got

approved from the Engineer in charge, before the reinforcement bars are placed

in position.

Patching or any other method of repair shall not be allowed on the concrete

surface
